Display and lights flicker or dim during operation.

Safety first: Unplug the unit before opening any panels.

• Check outlet and plug: Ensure the plug is fully inserted and the outlet is not worn. Try a different outlet.
• Avoid power strips: Plug the air fryer directly into the wall outlet to reduce voltage drop.
• Inspect internal connections: Remove the rear or bottom cover and verify all power connectors are tight, especially at the line filter board and main control board.
• Look for heat damage: Discolored connectors or melted plastic indicate overheating; replace the affected harness and connector.
• Replace control or filter board: If flickering persists and connections are solid, replace the line filter board or main control board as indicated by your model's design.
